TILE. EDGE FORMING" APPARATUS -1 p I a lication d March 20,1931 Serial Nd. 524,191.

This invention is directed to an improve ment intile edge forming machines, wherein certain edges of the-tile may be shaped and formed tomeet any desired or special requirements.

' In an application filed by me. in the United States- Patent Ofiice October 20,1930, Serial #490,025 whichha's become Patent 1,832,397,

' Ihave described and claimeda tile With respective edges adaptedfor nailing and formedfor interlocking with'adj acent tile, to thereby provide for accurate and correct tile l aying without necessitating the usual expert service, and insuring that the tllewhen r laid will be firmly fixed in the base on which they' are laid and accurately and relatively c disposed'to provide a" proper tile surface. 7

In the tile described in the said appllcation, two adjacent edges of the tile are formed as recessed edges, While the remaining adjacent edges are formedto'provide ledges shaped tointerlock with the recessed edges of neighboring tile,-the ledges being perforated for the receptionof nails or like Securing means. As conventionally;constructed in the tile forming machine Where thema terial is fed from the machine in a ribbonlike form ofappropriate thickness and of proper tile Width, the side edges of the ribbon are extruded to form proper tilej edges during the formation of the ribbon,'and'as thisribbon is dividedinto tile lengths, it'is,

of course, apparent that each tile after trans verse cutting of theribbon will have two of its opposite edges properly formed and the remaining, edges Without formation. order to complete the tile, therefore, means must be provided for properly forming the remaining edges, and asone of the edges already formed includesfthe'ledge formation 0 which is to be constructed for the reception of nails or theilike, the completion ofthe tile must notonly include theformation of the, gtllll unformed' edges but also the perforation of the ledge forming edge extruded inithe ribbonzforming machines I Y Theprimary object of the present invention, therefore, is the provision of means by which the unformed edges of the divided tile maybe properly andcompletely formed in a single operation, with such means also servingto perforate the ledge formation of one of the previously formed tile edges. l 7

It is,'of' course, important that theedges of the completed tile be at r'ight'angleslto each other and also *thatthe movement :of. the forming implements of the present invention be such as to'cut a true straightfon' mation on the tile edge, and in order to se cure these results it is desirable that the edge'of' the tileto be cut be held ina ver- 7 ticalplane and that the already formed edge be held'at a right angle to the plane of movement of the forming implementofithe pres- I entinvention. v

Therefore, the present invention contemplates a vertically moving forming implement and means bywhich the tile may be held through the medium of one of itsalrea'dy formed edges so that suchformed edgeis at direct right angles to the plane of movement of the forming implement of the present invention. l V As successive tiles subjected-to the. action 7 of the forming instrumentof the present invention are similarly formed, that is, iden tical edges of successive tiles are given identical formation, it is apparent thatthe tiles 4. may, for thepurpose of the operation of the present forming apparatus, be held in 'pairs in order that two tiles, that is, the unformed opposite edges of two tiles, may be acted on the forming apparatus of the present invention in a single operation: In, Patent 1,770,406, issued to me July 15,1930, I have described and claimed a tile handling apparatus, in which tile delivered froma-tile making-machine are positioned in airs in vertical plane, with their Wearing aces in contact in order to protect these faces during the subsequent handling of the tile in drying and burning,and as the patented apparatus inthus positioning the tile to protect these Wearing faces arranges such tile in vertical position, that is, in a position most convenient for the operation of the tile forming apparatus of the present invention, such patented structure is utilized as part of the present invention for the purpose of accurately positwo tile as delivered from the extruding machines, with two of their edges already formed intovertical contacting relation, with their wear faces adjacent and thus protected and with their unformed edges in position to 0 receive edge forming implements moving vertically, with which implements are associated means for perforating one of the edges so formed and also means for perforating one of the edges formed in the extruding' 5 machine, so that the tile as delivered from the extruding machine and after severing into tile lengths may be completed as'to their edge formation while arranged inpairs to protect their wear faces and subsequently 0 handled in pairs during the drying and burning operations. The invention is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of the improved tile edge forming apparatus.

J .The present invention is directed to comtherebetween in relation-to permit the edge or like fastening means are driven into a supporting surface for nailing the tile in place. In the extruding machine, two opposite edges of the tile will bev formed in the formation of the ribbon as, for example, 3 and 4, but in the dividing of the ribbon into tile lengths,

the edges 2 and 5 will be square, unformed edges. and also the ledge formation 4 formed in the extruding machine will not be perfora-ted for the reception of the securing nails. The present invention is designed to properly complete these unformed edges and provide for the perforating of the edge 4 previously formed in the extruding machine.

While the present invention is illustrated and will be described more particularly in connection with a title having the edge formation shown and above referred to, it is understood that through a mere change of forming" members, any desired edge formation may be given to the tile, and the invention is to be understood as in no wise limited by the specific description and illustration with reference to a particular edge formation.

Aspreviously stated, Patent No. 1,? 7 0,406 issued to me July 15, 1930, describes and claims a tile handling apparatus which, with the addition of certain characteristics peculiar to the present invention, is made use of as a desirable and important adjunct to the edge forming apparatus, such tile handling apparatus, being briefly described as'follows The tile handling apparatus as illustrated more particularly in Figures 12 and 13 includes an appropriate supporting frame 8- comprising. side bars 9 adjustably mounted with relation to an intermediate bar 10 to provide for endwiseadjustment of the side bars. The side bars carry shafts 11 arranged in spaced parallel relation and ca .pable, through adjustment of the side bars, of

being spaced different distances apart to accommodate tile of different thicknesses.

Swingingly supported on each shaft 11 through brackets 12 are pallets 13 having a smooth, even, upper surface to receive and support thetilei Also supported on the shafts 11 areend gauge plates 14.- These end gauge plates are'designed to receive and gauge the tilewhen the latter are laid on the pallets and also support the tile when the pallets are turned into vertical position to arrange such tile in position to provide forthe operation of the edge forming-apparatus The end gauge plates 14 arearran'ge'dto be operated in the positioning ,movement'of the pallets 13, for which purpose the inner edges of the pallets are designed to bear against the lower portions of the gauge plates above their mounting on the shaftsll, as indicated at 16,

,soithat asthe pallets are moved to vertical position, indicated in dotted lines in Figure 13, the gaugeplates will becompelledto follow such movement, though,"through the independent mounting of the gauge plates relav t-ive to the pallets, the gauge plates may remain in operative position when the pellets are returned to normal or inoperative posicontacting relation without undue pressure in such figure;

through rods 18 carriedby the pallets and guided through "eyes 19 with an adjustable limiting means 20 on the rods to insure accurate positioning of the pallets Tapermit the pallets to return to normal position,

while insuringv thatfthe end gauge plates will remain in tile supporting position, the latter are provided with arms 21 Wl11Cl1,'lS'dB ,scribed in the patent, are connected -to' Weights over suitable pulley supports to hold the end gauge plates in the position indicated in dottedlines in Figure13, while permitting the return of the pallets to the normal positions or those positions indicated in full'lines For the purposes of the present invention,

the end gauge plateswhich, when the parts are in IlOlHlitl POSltlOIl, are arranged at the inner edges of the respectivepallets and project at right'anglesc and above thereceiving surfaces of such pallets, have formation complementary tothe edge forma tion of one of the edges of the tiles. Thus the end gauge plates are formed on their operative surfaces to accurately receive the recessed edges, either two or three as the case may be, of the tile, such surface formationof the end gauges being indicated at 22 and the tile edges to cooperate therewith being the recessed edges of the tile extruding machine.

As is understood in tile forming machines,

- the tile in proper sizes, and for thepresent invention with two opposing edges formed in the extruding machine, are carried on the F off bearingbelt, not shown, and two of such f tile are arranged in the handling machine described, being manually takenfrom the belt and placed ontherespective' platen, with theirformed'edges, as :2, accurately interfitted with the formed surfaces of theend 7 gauge plates 14. The ,mechanism control forming apparatus.

formed by the ling the arms 17 is then operated and the Y platen and. end gauge plates swung on the shafts 11 until the platen are in vertical,

spaced,iparallel relation with the tile carried thereonin contact, with such tile supported on the respective gauge plates 14 whichare now in-hori'zontal positionin edge contact with their'formed surfaces uppermost, all as clear- I ly shown in Figure 13 of the drawings. I

In this position, the upper and lower edges} of the tile are those edges which have been previouslyformed in the extruding machine,

While the side edges are the uniformed edges resultingfrom'thc operation of the cutting. w re in dividing the ribboninto tile lengths? As understood from the patent referred to,

the contacting surfacesof the tile are the uppermost or Wear surfaces, so that during the operation 0f the edge forming apparatus to be described, these surfaces are protected against marring and are further protected during the subsequent handling of the tile in drying and burning, asset forth in the .de

scriptionof the; patent referred to.

The edge forming apparatus of the present invention includes as an element guiding means for cooperating with the platen, and,

for the purpose-of insuringinitial cooperation of the guiding means eachplatent is centrally formed with a pro]ection n3'which extends materially above the upper edges of the tile when in position'in the tile handling apparatus to permit the cooperation of the edge For economy in operation, itis understood that the tile handling apparatus is duplicated on opposite, sides ofthe ofi bearing belt at a plurality of stages throughout the length of the belt so that all tile carried .on the belt may be properlyhandled and that the edge forming apparatus is, duplicated 1 and designed for simultaneous operation atJeach duplicated tile handling station. This is illustrated ,more'particularly in Figure 2,.

where it will be seen that by'reason of the arrangement, four tile are simultaneouslyhandled at each tile handling station and the edges of the four tile are completed through the single operation of :a duplicated edge forming apparatus. Of course, for the purposes of the present description, a detailed explanation of one of such edge forming ap paratus will be suilicient. I

The edge forming {apparatus comprises a supporting frame 24 of skeleton form, from,

the upper cross bar of which is supported a cylinder 25. The cylinder 25 has a removabledome section 26 formed at 27 for theadmission of air under pressure, which dome section is connectedto a tubular hanger 28 supported in a bracket 29 connect-ed to the cross framebar and, adjustable therein by upperand lower nuts 30. The tubular hanger is open at theupperendfor free-ex- 'haust purposes. i

The lower end of the cylinder 25 is pro-.

ing cup washer 33, and secured to the lower 5 surface of the piston is an annular block 34 V shock of operation;

designed, when the piston is in fully lowered position, to engage the flexible washer 35 resting upon the upper edge of the abutment 30 and guide sleeve 31, to thus absorb the The block 34L is interiorly threaded to receive what may be termed a hollow shaft 36, and threaded into the lower open end of this hollow shaft is the circular head 37. of a guide shaft, which below the circular head is diametrically reduced and of angular form, preferably square in cross section, as at 38. As the shafts'36 and '38 are moved vertically in the operation of the piston, and as the edge forming implements are carried by the shaf 38, it is, of course, of importance that this shaft be accurately" guided in vertical movement and prevented from possibility of turning during such movement, as otherwise the edges of the tile would be improperly or imperfectly formed.

To provide for the more effective, accurate guiding of the snait 38 particularly, 'the lat ter'is arranged to passthrough abushing 39 threaded into the lower end of a coupling 40 1 c a secured on tnc exterior ofthe guide sleeve 31. The bushing formed with van opening accurately conforming in size and shape to that of the section 38 of the shaft, and both the bushing and union 40 are vertically divided for a portion of their lengths, with the di vided portions of the union provided with ears ll connected by tightening means 42,

such as bolts and nuts, whereby any play in the bush ng relative tothe portion 38 of the shaft may be taken up and the shaft accurately and positively guided in the desired line.

A transverse arm 43 underlies the extreme lower end of the shaft section 38, being secured thereto'by a bolt 4%: threaded into the lower end of the shaft. A positioning ring 45 accurately fitting the exterior and con forming to the shape of the section 38 of the shaft immediately overlies and is secured to the arm 43 by bolts 46. Thus the arm is held rigidly with respect to the shaft 38- and prevented rom any displacement relative there- .to in any direction. 'The transverse arm &3

is formed on each side of the shaft 38 with elongated apertures 47 to provide for adjustment of the forming implements relative to each other. g

Secured to the under side of the arm 43 and depending in spaced, parallel relation therefrom are guide fingers 48 which depend f in such spaced relation that their inner sur faces accurately cooperate with the outer surfaces of the platen 13 in line with the projec-- tile are, of course, to be constructed to form such edges of the desired outline, the cutting blade of each element being so formed as to properly outline the edge of the two adjacent tile as held between the platen in a single operation. As these cutting elements in the particular use to which they are here assigned are designed to form different shapes of edges, one will be hereinafter termed the recess forming element which is designed to form the recessed edges of the tiles, and the other will be hereinafter termed the ledge forming element which isdesigned to form those edges of the tiles carrying the ledges.

The recess forming element includes a bar 49 threaded at the upperend, as at 50, with the threaded end designed to be extended through one of the slots 47 of the arm 43 and secured thereto in rigid adjusted position lengthwise the slot by disks 51 which bridge the slot from above and below, and nuts 52 which cooperate with the threaded portion ofthe element to rigidly secure the element in place. The lower end of the element is inwardly deflected toward the fingers 48 and is terminally provided with a cutting blade 53 which is shaped in its movement ver-.

tically of the edges of the tile to form the recessed edge formation of the two related tile, such edge formation being a duplicate of that shown in dotted lines at the lower end of the tile in Figure13. V

, The offset formation of'the rod 49 serves to prevent possible contact with such rod above the cutter with the material of the tile. The ledge forming element includes a bar 5% threaded throughout its upper portion at 55 for cooperation with the opposite, elongated opening 47 in the arm 43, disks 56 and nuts 57 insuring a rigid connection between the rod 54 and the arm 55 in any adjusted position of said rod in the elongated opening 47 of the arm. The lower end of the rod 5& is provided with a cutting blade 58 which is shaped to form the edges of the tile opposite those edges formed by the cutter 53 to provide the amas? present a vertical channel 9'between the ledges 6,- as shown in Figure 13.

In connection withthe particular tile be ing formed by this apparatus, the forming element 54 forms the ledges 6 on the similar edge of both tile, theright angled edge of each of such tile having been previously formed with a corresponding ledge 6 in the original formatiol'i of the tile ribbon, as pre-- viously described. These ledges 6, however,

both those originally formed and those the ledges 6formed by the apparatus itself 1 and in the ledges 6 previously formed by the initial ribbon forming machine.

For the formation of the nail-receiving open1ngs7 in the ledges resulting from the operation of the ledge-formingimplement 54,, such implement immediately above the forming blade 58 is shaped to accurately fit in the channel 59 between opposing" ledges 6, this shaped portion of the ledge-forming element being" of elongated, block-like form,

t as at 60. This block-like body 60 is transversely bored to provideopenings elopening throughboth sides of the block onspaced,

parallel, relatively inclined lines, and; similar openings 62 opening through both sides of the block on spaced parallel lines reversely inclined with respect to the lines of the open- 'ings 61. The outlet ends-of each set ofopenings 61 and 62 are on opposite sides of the" block respectively,- that 1 is, assuming the e channel 59 inFigure 13 to be the channel through which the body or block 60 is moved,

the outlet ends of one set or openings,-as 61, will be next the relatively nner; surface, as appearing in such figure, of one ofthe ledges 6, while the outlet ends of the other openings 62 will be sim'ilarlyplaced withrespect to the opposite ledge 6.; The entrance ends; of'the respective openings61 and 62 are disposed outwardly eyond the planeof the edge of 56, the tile, and these outlet ends'a're diametrically enlarged and interiorly threaded to receive nipples 63 projecting from a cylinder 64 in Which a piston 65 is operative.

The'piston carries a rod 66 which extends through the nipple 63, and under appropr ate operative movement of the piston through the, outlet end of the. particular opening 61-" or 62, as the caseinayjbe,and in this movement serving to pierce thev particular ledge 6 with which it cooperates for the formation I ferred' to.

of the nail-receiving holes 7 therein. As stated, the openings 61 and 62 incline downwardly from their entrant and their exit ends, and the cylinders 64 are secured at, the entrant end of therespective openings so that the piston rods 66 will simultaneously, when all cylinders are served, pierce the respective ledges" 6 in the proper position and atthe proper inclination. I a I The upper ends of the cylinders 64 are pro'-' vided with a removable cap. 67 having a communicating nipple 68 arranged forthe reception of a pipe for supplying air under a pressure, as'wi'll later appear, a spring69 being coiled about the rods 66 between the piston and lower wall ofthe cylinder to return the piston and thereby the "piercing rods 66 to normal or inoperative position upon the relief of the pressure, The 03 1-" inder near its lower endiis formed with out let openings 70 to permit the'escape of air below the piston in the operativemoveinent of the piston". a I I p In addition to 'pie'rcing'the formed ledges 6 with a nail-receiving opening 7, it is also necessary to similarly pierce the ledges 6 of those tile edges 'which were formed in the ribbon forming maichine, as previouslyex "plained', and which, of course, are disposed at right angles to the ledges formed by the apparatus of this invention; To s cure this result, block-like bar 7I is secured through the medium of a threaded bolt 7 2 to the lower end of the non-circular shaft 38, the-bolt'72f being preferably threaded into the bolt 44 serving to secure the arm 43 to said shaft 38; Lock nuts 73 arerprovided for rigidly main taining the positionofthe block 71 The plane-of the block 60 and in such relation'te such block 60 thatwhen the block 60 is in positionto form the openings 7 in the ledges 6 provided a'sa result of the operation'of we blade 58, the bar 71 will be resting in the opening between the ledges 6 which have alreadybeen formed in the ribbon forming .mac'hine in theinitial formation ofthe tile material. The block 71 is formed with two sets of openings',-74 and 75 of opposite inclination, with their exit ends adjacent the inner surfaces of the respective ledgesof the tile and their entrant ends formed for the ilhistrated specificallyin Figure 30f the dr'awings.- i

V of tile being produced.

in succession longitudinally of the belt as may be. necessary to take care of the volume pairs at any one station is simply for convenience and economy in manufacture, permitting convenient handling of the tile and operation of the edge forming apparatus. The edge forming movement of the apparatus is, ofcourse, resultant from the operation of the piston 32, and to secure this operation a pipe line 76 open to a source'oi' air under pressure is arranged to serve any and all edge forming apparatus. This pipe line has a by-pass 77 leading to the cylinder through the opening 27, the bypass being provided with a manually controlled valve 7 8 for the control of the operation of the piston at will. by-pass 77 is provided before the valve 7 8 with a lateral pipeextension 7 9 carrying a manually operablevalve 80 and beyond the valve connected by flexible piping 81 to the.

nipples 68 of what may be termed the piercing cylinders 64.

.To return the pistons 32 to normal or. inoperative pos1t1on, a cross bar 82 1s passed with a driving fit through diametrically opposed slots 83 in the hollow shaft 36 and extends throughslots ea in the guide sleeve 31, the latter slots being of suflicient length to permit a fully operative movement of the hollow shaft 36. The ends'oi the bar 82 are connected by cables 85 with weights 86, the cables passing over pulleys 87 supported from the upper cross bar of the. frame 24, as

shown'in Figure 2, the cables 85 on each side of each apparatus of the pair beingled over the same pulley. Of course,it is understood that the valves 80 controlling the piercing cylindersare provided with anexhaust out let 88, so that upon closing the valve 80, the cylinders are open to the exhaust, whereupon t 65 to inoperative piercing rods 66. i

In the operation position and withdraw the of the improved mecha- 'nism, the operator having charge of a particular edge forming machine or machines will pick up off of the Oh bearing belt two tile in succession and dispose them on the platen 13 of the handling machine, which platen are in the position illustrated in full lines in Figure13. In this position, the end gauge plates 14 are in the position illustrated in full lines v in said Figure 13, and inplacingthe respec- The arrangement in esprings 69 operate to return the pistons.

with and supported by the end gauges 14L andtheir ledge formed edges uppermost. The tile are disposed on the platen longitudinally so that their wear or upper surfaces, when laid, are uppermost so that when turned into the position shown in dotted lines in Figure 13, tnese wear faces of the respective tile are in contact and are thus protected against being marred, broken or otherwise interfered with during the operations to which the tile may be subsequently subjected.

lVhen the tile are arranged in this position in the tile handling apparatus, the edges of the adjacent tile held between the upright platen 13 are, of course, uniformed. The valve 7 8 is operated and air admitted to depress the piston 32 of the edge forming apparatus. If an operator is handling two edge forming apparatus, the tile may be positioned in the respective handling apparatus and two edge forming apparatus operated through a single control valve or through the operation of two such control valves, as may be desired. Under pressure of air, the piston 32 descends, carrying with it the shaft 38, which, as stated, isof non-circular form, and by reason of the guiding functions of the cooperating parts held against'possibility of turning.

As the edge forming apparatus moves downwardly, the ends of the fingers 48 engage the outer surfaces of the projections 23 of the platen and thereby absolutely center and positively guide the forming elements in correct relation to the edges of the tile to be formed thereby. In the continued downward movement of the shaft 38, the forming blades 53 and 58 form the respective edges of the two adjacent tile to cause these edges to correspond one with the recessed edge 2 and the other with the ledge edge 4. As the blades 53 and 58 reach their downward limit, that is, the lower end of the tile edges, the bar 60 is positioned between the ledges of the edges 1 justformed, while the bar 71 is positioned between the ledges of the tile edges previously formed. The valve is then opened and air under pressure admitted to the respective piercing cylinders 64, whereupon the pistons 65 are depressed against tension of the springs 69 and the piercing rods .66 form holes at the appropriate places and at the appro- .priate angles in the ledges,both those previously formed and those formed by the cutting blade 58. Upon closing of the valve 80, the cylinders 64 are opened to an exhaust and the springs 68 operate to return the piercing rods to the normal or inoperative position free of any possibility of interference from the tile material, whereupon the valve 7 8 is closed, permitting the cylinder 25 to exhaust to the atmosphere and the weights 86 to re turn the piston and edge formers to normal or inoperative position. The arms 17 of the handling apparatus are then actuated in the opposite directions, which return the platen 13 to their normal orinoperative positions, leaving I the formed tile in contact resting upon and supported by the edge gauges 1450f the respective platen. The two tile thus coni- 5 .pleted as to edge formation with their'wear' surfaces in contact are subsequently handledas a unit, being manually transferred to the belt or other conveyor to be carried awayfor burning to complete of-diiierent thickness may be readily accommodated by the .adJustme'ntof the forming. elements tliroughth'e medium of the elongated openings 47 formed in the arm 43.
